A rolling grinding type continuous sand screening device for construction

Abstract

The invention discloses a rolling grinding type continuous sand screening device for construction, which comprises a screening sand box, an outer filter mesh cylinder, a grinding cylinder, an inner filter mesh cylinder, a rotating shaft, a grinding ball, a pushing screw blade and a grinding roller. The sieve sand box is installed on the support frame, the middle of the sieve sand box is horizontally provided with a rotating shaft, the middle of the rotating shaft is welded with a grinding roller, and the rotating shaft on the other side of the grinding roller is welded with a pushing screw blade. The cylinder is sleeved on the outside of the rotating shaft, and a grinding cylinder is arranged in the middle of the inner filter cylinder; the outer filter cylinder is fixedly connected to the outside of the inner filter cylinder; the screening, grinding and ball milling of building sand can be realized until the sand is completely screened. In addition, it is finally discharged from the discharge hopper for construction use, which is convenient and quick to operate and has high screening efficiency. At the same time, it has good grinding and ball milling effects, which ensures that building sand can be fully applied to construction and avoids traditional large particles. The problem that the diameter sand particles cannot be put into construction after being screened out.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a rolling grinding type continuous sand screening device for construction. Background technique [0002] During the construction of the construction site, sand is used, and the sand cannot be used directly when it is bought back. The sand needs to be sieved. The net is only limited to artificial, the efficiency of artificial sand screening is low, the labor intensity is high and cannot keep up with the fast-paced construction, so it has to take up more manpower and increase the construction cost; The sand screening treatment can meet the requirements, otherwise it will affect the engineering quality of the construction. [0003] There are many sand screening devices in construction sites or other construction fields, and professional sand screening machines are rarely used for sand screening in construction sites. Such sand screening machines are expensive and cos...
